The length of the rectangle is 128 cm, which is 8/9 of its width. Find the area and perimeter of the rectangle.

Let’s find the width of this rectangle, for this we need to divide the length of the rectangle given to us by 8/9:

128: 8/9 = 144 cm is the width of this rectangle;

Let’s find the value of the perimeter of the rectangle given to us, for this we need to add the length value to the width of this rectangle, and multiply the result by 2:

(128 + 144) * 2 = 544 cm – the value of the perimeter of the rectangle given to us;

Let’s find the value of the area of ​​the rectangle given to us, for this we need to multiply the value of the width of the given rectangle by the value of the length of the rectangle given to us:

128 * 144 = 18432 cm2 – the value of the area of ​​the rectangle given to us.

Answer: 544 cm is the value of the perimeter of the rectangle given to us; 18432 cm2 – the value of the area of ​​the rectangle given to us.
